To all whom it may concern.-

Be it known that 1, JAMES H. VVOODARD, a citizen of the United States,and a resident of Dayton,Oamploell county, State of Kentucky, haveinvented a certain new and useful Traveling Oiler for Elevator-Guides;and I do declare the following to be a description thereof sufficientlyclear, full, and exact to enable others skilled in the art to which itappertains to make and use the same, attention being called to theaccompanying drawings, with the reference-numerals marked thereon, whichform also a part of this specification.

This invention relates to devices used for applying lubricant to thewearing-surfaces of operating parts while such parts are in motion andwhere such surfaces are not readily accessible either on account oflocation or on account of the motion of the parts or on account of bothcauses combined.

My device is intended for use in connection with elevators to lubricatethe guides between which the cab or platform travels up and down. Incase of a closed elevator-cab, for instance, it is quite difficult toapply oil to the guides, which is generally done from the outside bysome one mounting the roof of the cab. This causes in most cases aninterruption of the service, unless it is done at a time when theelevator is not publicly used, when it must, however, be run after usesimply to permit applying of the oil.

One object of my invention is, therefore, to provide a device wherebyoil may be applied to the guides of an elevator irrespective ofdifficulties of position, access, or motion.

A secondary object is to permit such application to be performed at anytime, particularly while the elevator is in usual operation, withoutrequiring, however, an interruption of service or extra time afterservice.

With these objects in view my invention provides, first, oiling devicestraveling with the cab and fitted so as to be adapted to apply thelubricant directly against the wearing-surfaces of the guides.

It further provides means to supply these oiling devices, and it finallyprovides means whereby their operation is controlled from the cab, sothat lubrication maybe performed at any time.

My invention provides means arranged, used, and operating all asdescribed in the annexed specification, and pointed out in the claimsfollowing it, the construction of these means being also illustrated inthe accompanying drawings, in which Figure 1 is a horizontal sectionthrough an elevato1'-shaft,showin g elevator-guides in section and topview of the elevator-cab with my oiling device in position. Fig. 2 is afront elevation of the upper part of Fig. 1. Figs. 3 and 4 are enlargeddetail views, the first being a top view and the other an elevation,partly in section, of the device applying the lubricant directly againstthe surfaces to be oiled and distributing the same thereover. Fig. 5 isan enlarged sectional detail view of the ejecting device.

In the drawings,7 indicates a customary elevator-cab, and 8 indicatesthe guides whereby it is confined to its position while traveling up anddown, it being held thereto by slides 9, projecting laterally from thecab.

My oiling device consists, first, of a forkshaped discharge-head 11, onefor each guide and each shaped as shown, so as to surround, but withoutcontact, the surfaces to be oiled, for which purpose they consist eachof three branches joining each other at such angle as the shape of theguides may require. On their inner sides and opposite the surfaces to beoiled they are provided with rows of discharge-orifices, through whichthe lubricant is expelled. The oil is supplied from a tank 12, which maybe filled at suitable intervals and from which it passes to thedischargeheads 11 through pipes 13, the whole'being supported onbrackets 14 and carried on top of the cab. Interposed between thisreservoir and these discharge-heads there is an ejecting device wherebythe oil is caused to be expelled from the discharge-heads against thesurfaces of the guides to be oiled whenever lubrication is desired. Thisejecting device consists, substantially, of a pump, of which 15 is thecylinder and 16 the plunger, fitted to the bore of it. This plungeroccupies a normal position at the discharge end of cylinder 15,in whichpositionlit prevents discharge of oil by cutting off the supply to pipes13, since it is not intended that lubrication should proceed constantly.When lubrica- ICO tion is desired, plunger 16 is moved 0utwardly,causing oil to be drawn into cylinder 15 from tank 12. On theimmediately following instroke this oil in front of the plunger.

is forced through pipes 13 to discharge-heads 11 and ejected through theorificesthereat. A customary check-valve 17 between cylinder l5 andsupply-tank l2 prevents at this time the oil from reentering thislatter. For so operating the ejector I provide an anglelever 18, pivotedat 19 and connected to the plunger-rod 21. cessible by means of apull-rod 22, extending into the cab, where it is reached by theattendant, who may thus by a simple pull operate the device andlubricate at any time during or between runs. To insure at all times thereturn of the plunger to its normal position, in which it preventsescape of oil from cylinder 15 by closing the supply thereto from tank12, I provide a spring 23, which is compressed on the outward movementof the plunger, and thus performsautomatically this function ofexpelling the oil and returning to its normal position. Instead of usingan angle-lever and pull-rod, as shown, an ordinary lever might be used,pivoted between its ends and connected with one of them to the outer endof the plunger-rod and reaching with the other one into the cab.

To obtain a thorough and uniform distribution of the oil all over thesurfaces to be lubricated, I provide wipers of absorbent material belowthe discharge-heads on each side. This material, which may be felt orcottonwaste, is carried in a suitable cage 24E, supported on brackets25, which are connected so as to travel with the discharge-heads, butbelow the same.

The absorbent material is applied to a thickness sufficient to reach andcontact with the surfaces to be lubricated and retards the oil,preventing it from running at once off from the surfaces to which it hasbeen applied. The oil so retained is thus repeatedly carried over thesurfaces, thoroughly lubricating them. The whole device might also becarried below the floor of thecab, in which case, the oil-tank beinglower than the dischargeheads, the circumstance of having said tanknormally closed would not enter into consideration.

Having described my invention, I claim as new 1. In a traveling oilingdevice to lubricate elevator-guides,the combination of dischargeheadsshaped to surround, but without contact, the wearing-surfaces of eachelevatorguide, normally open discharge-orifices in these heads directedagainst these surfaces, a supply-pipe on which each head is carried, anormally open oil-tank in communication with these supply-pipes, aninterposed ejecting device which controls and normally prevents suchcommunication, and means manually controlled for operating this ejectingdevice to cause oil to be discharged against This lever is renderedacthe wearingsurfaces of the elevator-guides, the Whole connected to andtraveling with the elevator-cab,so that oil may be discharged in anyposition of the cab and against any point of the traversedguide-surfaces.

In a traveling oiling device to lubricate elevator-guides,tl1ecombination of dischargeheads shaped to surround, but without contact,the wearing-surfaces of each elevatorguide, normally opendischarge-orifices in these heads directed against these surfaces, asupply-pipe on which each head is carried, an oil-tank to feed thesesupply-pipes man uallycontrolled means operating to cause oil to beejected against the wearing-surfaces of the elevator-guides, the wholeconnected to and traveling with the elevator-cab, so that oil may bedischarged in any position of the cab and against any point of thetraversed guidesurfaces, and devices below each dischargehead travelingalso therewith, but in contact with the wearing-surfaces of the guidesso as to take up and retain the oil discharged against these surfacesfrom the dischargeheads and distribute the same thereover whiletraveling with the cab.

In testimony whereof I hereunto set my hand in the presence of twowitnesses.
